Factoring Expressions and Difference of Squares

The video tutorial explains how to factor out the greatest common factor (GCF) and the difference of two squares. It begins with identifying the GCF of the terms in an expression, then demonstrates dividing each term by the GCF. The tutorial continues by explaining how to recognize and factor the difference of two perfect squares, using the example of 2x squared minus 32. The process involves taking the square root of each term and applying the difference of squares formula.
